Bug 38030 – grass 5.0.2 fails to compile due to fftw3

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Curtis 2004-01-12 20:51:31 UTC]

grass 5.0.2 ebuild fails to compile because it looks for fftw.h.  fftw 3.0.1 includes fftw3.h instead.

Reproducible: Always
Steps to Reproduce:
1.on a system that does not already have fftw 2.1.3 or greater installed, emerge grass
2.
3.

Actual Results:  
configure for grass failed because it could not find fftw.h

Expected Results:  
Configure should have found fftw.h with fftw-2.1.5 installed.  ebuild for grass
5.0.2 should specify the dependency for fftw as "=dev-lib/fftw-2.1.5"

Changing ebuild for grass 5.0.2 so that it specifies the dependency for fftw as
"=dev-lib/fftw-2.1.5" resolved the issue.

could you try grass 5.0.3 ?

[Comment 2 Les Denham 2004-01-14 06:47:53 UTC]

Same with 5.0.3

My workaround:

1) emerge unmerge fftw
2) emerge /usr/portage/dev-libs/fftw/fftw-2.1.5.ebuild
3) emerge grass

Any GRASS 5.x only supports FFT2. FFTW3 is unsupported as it's API was changed.

Hope this helps,

Modified ebuild that correct the problem

I added a modified ebuild that corrects the problem. I.e. it forces grass to
install fftw 2.1.5 (and not fftw 3.0). Well, the problem is that portage
unmerges fftw 2.1.5 when you install something that depends on fftw3... Maybe
it would be usefull to separate fftw2 from fftw3 (dev-libs/fftw2 vs.
dev-libs/fftw3). The question is: Is it possible to install the two versions
together ?

Re-assign a stale bug, please close if this is no longer an issue.

[Comment 6 Patrick Kursawe (RETIRED) 2005-08-17 03:04:47 UTC]

I am not the maintainer, but since all current grass versions depend on fftw2 it
looks like this bug is history.
